The instructions on the 8453 form make it clear:
Don't attach any form or document that isn't shown on Form 8453 next to the checkboxes. If you are required to mail in any documentation not listed on Form 8453 you can't file the tax return electronically.
Form 8453 does not list 1099-B forms, so I can't e-file???
Can someone clear this up for me?
